To @ZZ whom it 1n/tty concern:

B e it known that I, AUSTIN M. WESTON, a citizen ofl the United States, residing at Kansas City, inthe county of Jackson and State of Missouri, have invented certain new and useful Improvements in Lister-Cultivators, ofy

twisting the supporting-bar or bending thev beams is eliminated when the disks drop in crossing a dead=furrowor`ditch, the carryingwheelsand the disks may be adjusted in or out without removall-fromthe supporting bars, and the carrying-wheels can be so ad justed as to maintain the proper relation with the corn. f

With this general object in view theinvention consistsin certain novel and peculiar features of construction and combinations of parts, as hereinafter described. and claimed;-

and in order that it may be fully understood reference is to be had to theaccompanying drawings, in which-` j t Figure l is a top plan View, partly broken away, ofrone side of -a lister-cultivator embodying my invention. `Fig.2 is a vertical` section taken on the line Il II of Fig.v 1. 3 is a vertical section taken on the line lll Ill of Fig. 1,. Fig. 4 is a detail perspective view of the stationary bar which is suspended from the framework and carries the supporting-wheels, said figure also showing the supporting-bar for the cultivating appliances, said bar being hinged to the first-named bar.r Fig. 5 is a perspective view of one of the adjustable sleeveboxings for the 'cultivating appliances. Figs. 6 and 7 are enlarged longitudinal and cross sections, respectively, showing the joint between `rods 24 26 and vIteferring to the drawings, where like reference-numerals designate corresponding parts, 1 designates the transverse platform or board whereon is mounted the seat. (Not shown.) Also mounted upon said platform near each end is a mechanism constructed as follows, only one being shown and described in this connection: 2 designates a tongue eX- tending longitudinally `and underlying said platform. 3 and 4 designate transverse front and rearl bars extending parallel by preference and bolted cent-rally to said tongue, a block 5 being interposedbetween the rear bar andthe tonguev in order thatr the latter shall extend upwardly and forwardly at a slight angle and be held out lof contact with said platform.

6 designates side bars underlying the platssl form and connecting the ends of bars 3 and l 4, and 7 similar bars arranged above the platv form and also secured to the ends of bars 3 and 4, spacing-blocks 8 being interposed between said bars 6 and 7 and bars 3 and 4 in' order to maintain lbars 6 and 7 parallel and `permit the frame of whichfthey form a part to slide freely andturn upon the platform,'the

usual pins l? depending from platform 1 outl wardot' frame-bars 6, eliminating any possi'- bility of theframe slidin g-entirelyv clear ofthe platform. -9 designatesv hangers depending rigidly from bars 6 of said slotted frame and provided with rectangular sleeves 10 at their lower ends having rearwardly-projecting lugs,v

13 designates a similar and paral- Vergingbraces 16 are secured at their rear j ends to sleeves 10 and at their front ends to a 1 bolt. 17, extending transversely through the tongue, said bolt being adapted to engage one of a series Ofholes 18 in the tongue in order that the parallelism ofthe tongue with the wheels maybe insured for a purpose which hereinafter appears.

Apair of rectangular-*sleeves adjustably mounted on bar 12 at opposite Sidesof and equidistant from the tongue are each composed of two sections19 20, clamped together by bolts 21, whichl when loosened permit said sectional sleeves to be adjusted uponv the bar, as hereinbefore mentioned. One member of each sleeve, preferably the upper member, terminates forward of the bar ina IOO rough-faced enlargement or rosette 22, and

engaging the same is a similar rosette 23, said parts being clamped together` by one of the bolts 21, hereinbefore referred to, the arrangement being such that when said bolt is looscned the rosette 23 can be adjusted so that its arm 24 shall extend downwardly and forwardly at a suitable angle, may occupy a vertical plane parallel with the tongue, or extend obliquely inward or outward of such plane. The lower1 end of arm 24 is of semicylindrical form and carries a clampingeyebolt 25, through 4which the upper end of arm 2G eX- tends and may be longitudinally or rotatably adjusted, the clamping-bolt being tightened to hold said arm rigidlyiu the semicylindrical portion of arm 24. Arm 26 terminates in a rosette 27, engaging and bolted to a similar rosette 28, provided with an outwardly-projecting arm 29, on which the carrying-wheel 30 is journaled in any suitable or preferred manner.

By the adjustment of rosette 23 on rosette 22 it is obvious that the distance between wheels 30 may be varied and that, irrespective of the distance between them,they may be maintained in a parallel relation by the proper adjustment of rosette 28 on rosette 27. It is also obvious that by rotating or turning arms 26 in the eyebolts 25 the wheels. maybe maintained in a vertical position or may be caused to assume an oblique position, as shown by dotted lines ct in Fig. 3. The advantage of having the wheels in this position is pointed out in the description of the operation of the machine.

3l. designates a pair of rectangular sleeves mounted adjustably upon tubular bar 13 and provided rearward of said bar with rearwardly-projecting arms 32, to which are secured by bolts 33 the plow-beams 34. These beams are further connected to said arms by means of breakable pins 35 and carry at their lower rear ends, in the usual or any preferred manner, the usual bull-tongued shovels 36.

The rear portions 37 of sleeves 31, in conjunction with caps 38, bolted thereto, form a journahbearing for the vertical portion of the angle-arms 40, said arms being provided with longitudinal ribs 41 for engagement with one of the radial grooves 39 of the bearing in order that said angle-arms shall extend in a vertical plane parallel with the tongue or shall project inward or outward thereof. The lower ends of said angle-arms 40 carry eye bolts 42, wherein are adjustably mounted rods 43 in the manner described with relation to arms 24 and 26, said rods 43 being provided at their rear ends with rosettes 44, engaging similar rosettes 45, bolted thereto, as at 46, and provided with inwardly-projecting spindles 47, whereon the cultivating-disks 48 are journaled in the usual or any preferred manner. By adjusting arms 40, journaled in said bearings, the depth of cut may be varied. By turning said arm in said bearing and securing it therein bythe engagement of the ribs with the proper grooves, as above described, the disks can be caused toassume varying distances from each other. By adjusting arms 43 in the eyebolts 42 the disks can be thrown out of the vertical plane in either direction, and by adjusting rosettes 45 upon rosettes 44 the relation between the disks can be readily varied.

49 'designates a plate mounted on the tongue forward of the slotted frame and provided with anotched sector 50 and concentriclugs 51. Journaled in said lugs is a transverse shaft 52, upon which is mounted a lever 53 and an angular crank-armv 54, the latter forming practically a continuation of the lever and underlying the tongue. This extension or angular crank-arm is connected by links 55 with lugs 56 of stationary sleeves 14, hereinbefore described, mounted upon tubular bar 13 outward of sleeves 31, in order that when lever 53 is manipulated it shall cause hinge-bar 13 to swing upwardly or downwardly, and consequently raise or lower the cultivating appliances, the lever being provided with the usual spring-actuated dog 58 for engaging the sector and with a grip-lever 59 for withdrawing said dog from engagement when desired.

In the practical operation of this machine the wheels 30 travel in the furrow at opposite sides of the young plants, the disks following `in the wake of the wheels and the first time over the ground throwing the earth outward, what little earth there is needed being supplied by the shovels. In this first cultivation of the plants the wheels and cultivating ap pliances are closer together than they are in subsequent operations, and frequently, particularly with young and fractions horses, more or less corn is destroyed by onehorse or the othergetting into the furrow and by turning the tongue obliquely deilecting the machine from its path and causing it torun over the corn, this trouble being more liable to ICO IOS

occur where the relation between the tongue A and the wheels is variable. To guard almost absolutely against this trouble, particularly in the first cultivating operation, I have provided the adjustment described, whereby I am enabled to not only cause the wheels to converge inwardly, and therefore have their front edges more remote from the sides of the furrow than their rear edges, but also to assu me an angle approximating that of the sides of the furrow, (see dotted lines @,Fig. 1,) which tends to hold the wheels in the furrow in case the tongue should swing around better than if they were straight, as shown in full lines. In the latter case one of the wheels could more easily climb the side of the furrow and cause the other to roll over the corn, whereas with the arrangement disclosed in said dotted lines it is obvious that the tongue may be turned obliquely to about forty-live degrees before there would be any tendency on the part of either wheel to climb the furrow, such action simply swinging the wheel around until its side extends approximately parallel to that of i the furrow. The shovelsmay be adjusted in by the vertical adjustment of angle-arms 40,

as hereinbefore explained.

In crossing dead-furrows or ditches the entire Weight ofthe cultivating-disks and appurtenances thereof is frequently thrown upon the plow-beams and the supporting-bar. At

times this trouble 4has resulted in a bending of the beams and twisting of the bars, and to any of its-advantages.

. secured rigidly to said frame andunderlying. the platform, a non-rotatable; bar suspended.

avoid it in the future I employ the breakable pins-85, which break under the imposition of a strain toogreat for the beams and bar to bear in safety, the driver being provided with additional pins to replace the broken ones, asv

will be readily understood.

When driving to or fromthe field or in crossing ditches or obstructions, the driver by the proper manipulation of leveri 53 can easily and quickly raise the cultivating appliances vto .an-inoperative position above the ground Without the necessity of raising the additional weight of the platform and himself,it being obvious that as the relation between thewheels and the platform is fixed the latter is notaffected by the rise orfall of the cultivating appliances.

From the above description it will be apparent that- I have produced a lister-cultivator embodying the features of, advantage enumerated as desirable in the statementy of invention, and While I haveillustrated and described the preferred embodiment of.. the same it is to be understood that Ireserve the right to make such changes in its form, proportion, detail construction, and arrangementof the parts as shall not involve a departure from its spirit and scope or sacrifice I-Iaving thus described the invention, what I c laim as new, and desire to secure by Letters Patent, is- 4 l.
